Just an update. I went to the LBS and found a bunch of bikes w/STI and they had inline adjusters. Three stops later, and I found the last pair in town whihc were not already on a bike. Pictures attached. Thanks for the help!
On the DOWN side, the Sora front brifter and the Altus are not working together. There does not seem to be enough overall throw to get all three gears. My question is that this is going to be either a $20-$50 fix, or a $100-$200 fix. The cheap way is a new front derailuer, but will a 105 be any different? The derailure would have to have a different leverage point than the Altus. I fear that Shimano's yet-to-be discovered logic states that the chain ring spacing between a MTB triple chainring and a road bike triple chainring is different, which means its going to be even more expensive to continue this swap, if at all.
Input prior to forking out more $$ is appriciated
Thanks!
